* Right-top plot is the idle time sample obtained during the experiment* Left-top graph is histogram of right top plot* The bottom graphs corresponding to idle times when sched_mc_power_savings=1

Observations with sched_mc_power_savings=1:

* No major impact of sched_mc_power_savings on CPU0 and CPU1* Significant idle time improvement on CPU2* However, significant idle time reduction on CPU3

Experiment 2:-------------Setup:

* USB stopped* Most daemons like yum-updatesd, hal, autofs, syslog, crond, irqbalance, sendmail, pcscd were stopped * Interrupt routing left to default but irqbalance daemon stopped * Powertop shows around 4 wakeups per second during idle (http://svaidy.googlepages.com/2-powertop-screen.txt) * The trace of idle time stamps was collected for 120 seconds with the system in idle state

Results:

There are 4 png files that plots the idle time for each CPU in thesystem.
